According to [Eleanor] Clift's report on the Newsweek blog, Biden "said a young naval officer giving him a tour of the residence showed him the hideaway, which is behind a massive steel door secured by an elaborate lock with a narrow connecting hallway lined with shelves filled with communications equipment."

Clift continued: "The officer explained that when Cheney was in lock down, this was where his most trusted aides were stationed, an image that Biden conveyed in a way that suggested we shouldn't be surprised that the policies that emerged were off the wall."
